Notification Box Android App for Recovering Deleted Notifications and OTPs

An Android app that runs a background service to archive all notifications before they disappear, enabling users to recover deleted messages, find past notifications, and automatically extract OTP codes. It addresses the problem of ephemeral notifications that vanish once dismissed, causing users to miss important information like OTPs or message previews.

Verdict

High-value case for teams facing a similar time saved problem. Implementation effort is medium effort, so it is worth prioritizing when the workflow pain is recurring, measurable, and owned by a team that can execute.

Production teamsMobile Applications / Consumer TechnologyAndroid app developer and end usersNotificationListenerService (Android SDK)Local-only / low-volume operation

Implementation Risks

Background service lifecycle management is challenging due to aggressive battery optimizations on some devices (e.g., Samsung, Xiaomi), requiring a foreground service with minimal notification to keep it alive
No cloud sync to preserve privacy, so data is device-local only.

Context

Users frequently miss or accidentally dismiss important notifications such as OTP codes or message previews that disappear immediately and cannot be retrieved.

Task solved

Capture and archive notifications in real-time, enable searchable history, auto-extract OTP codes, and recover deleted messages.

Tools

Kotlin, Android SDK, NotificationListenerService, Room database, Jetpack Compose, Android accessibility APIs

Result

Users can recover deleted notifications and OTPs, search notification history instantly, and avoid missing time-sensitive information
The app runs reliably on various devices despite OEM battery optimizations by using a foreground service.

Analyst Notes

Main challenge: Background service lifecycle management is challenging due to aggressive battery optimizations on some devices (e.g., Samsung, Xiaomi), requiring a foreground service with minimal...
Implementation effort: The technical piece is only part of the work; the harder question is whether Kotlin, Android SDK, NotificationListenerService, Room database, Jetpack Compose, Android accessibility APIs can be owned, monitored, and reconciled in production.
Practical read: Best read as a medium effort operational change with ROI upside when the pain is already measurable.
